Sjack Abeling Gravity Wheel VIRTUAL replications and models

Actually, the equipment in both of my cases would swing 135 degrees. For the tangent thrower it could still have a extended edge to cause a rotation. It still would not throw further than the accumulated acceleration CF sling version. 

BTW, your root(2) notation is unusual, did you mean sqrt of 2 or an array named root where you wish to divide by the value of the second member in the array?

I meant the square root - so the non-centripetal thrower would (ideally) throw over twice as far as the tangential thrower.

A tangential launcher rotating 135 degrees will throw less far (for the same input work) than one rotating through 90 - for the first 45 degrees both components of the acceleration are in the opposite direction to the final throw, and need to worked against - hence are completely wasted. In the real world this has some benefits to reduce the losses inherent in a system where the arm and disk are not perectly inelastic, and the spring can't contract instanteously, but your 135 degree tangential thrower would throw the same distance as the 90 degree thrower for the same cocking force (but which would half as much again cocking work for the 135 tangential thrower than the 90 degree one)
